Ups - Siemens SIMATIC TP 270 Operating Instructions Manual

Operating system and configuration
6.2 Windows CE Control Panel
Caution
If too much memory is provided for the DRAM file system, runtime has too little working
memory available. Therefore, in the case of incorrect settings, there is no guarantee that the
runtime can run properly.
Caution
The operation of runtime together with the Internet Explorer can only be guaranteed when
runtime either does not use the Present option or the runtime-capable configuration (*.few)
generated is a maximum of 2 NB.
Note
Operation of additional applications together with WinCC flexible
The memory requirements of projects in WinCC flexible has changed in comparison to
ProTool.
If user-specific additional applications should be operated on the HMI device together with a
WinCC flexible project, the functionality required on the HMI device must be tested and, if
necessary, the scope of the project or additional application reduced.

UPS

Uninterruptible power supply (UPS)
To prevent the loss of data in the event of a power failure (during the logging of process
values or alarms, for example), a UPS can ensure a controlled shutdown of the HMI device.
An external UPS detects the failure of the power supply and signals this to the HMI device
via the serial interface.
The UPS can only be loaded as an option.
"UPS" option
The UPS driver is transferred as an option to the HMI device with WinCC flexible or the
ProSave service tool. After transfer, the relevant "UPS" option appears in the Windows CE
Control Panel.
